It seems to me that it's the detection systems which will breach civil liberties. How will they detect illegal file sharing (as opposed to legal file sharing)? Presumably ISPs will have to record more information about their customers' internet activities, particularly anything using P2P, and make this information available to someone; who is that someone?
Personally I would find this intrusion quite offensive. I use P2P quite frequently, and it's all legal and honest, but there would certainly be some sort of marker recorded against me, and this could so easily be misinterpreted so as to make me a suspect. Me and countless others.
I wonder how much his greasy little palm got lined this time.
Even if it wasn't as overt as a brown envelope stuffed with used tenners, there's no doubt in my mind that this is a case of undue influence from a very rich man.
